Correct answer: A — Non-accidental injury

Bruising in a pre-mobile infant (not yet rolling, crawling, or cruising) is highly concerning for non-accidental injury. 'Those who don't cruise rarely bruise' is a clinical maxim. A full child protection assessment, skeletal survey, ophthalmological examination, and coagulation screen should be performed.
